Ab=1/4((a+b)^2-(a-b)^2) Is An Amazing Identity, And Unfortunately, I Have To Remind My Current Students How To Prove It.

Incidentally, When We're Faced With A "prove Or Disprove," We're Usually Better Off Trying First To Disprove With A Counterexample, For Two Reasons: A Disproof Is Potentially Easier (we Need Just One Counterexample); And Nitpicking Arouses Our Creative Juices.

Juggling Is Sometimes Called The Art Of Controlling Patterns, Controlling Patterns In Time And Space.

Some People Think That Mathematics Is A Serious Business That Must Always Be Cold And Dry; But We Think Mathematics Is Fun, And We Aren't Ashamed To Admit The Fact. Why Should A Strict Boundary Line Be Drawn Between Work And Play? Concrete Mathematics Is Full Of Appealing Patterns; The Manipulations Are Not Always Easy, But The Answers Can Be Astonishingly Attractive.
